EXCERPT: [...] Scientists in the United States are creating so-called ‘human-pig chimeras’ which will be capable of growing the much-needed organs. These chimeras are animals that combine human and pig characteristics. [...] A chimera is a genetic mix. This means that, although the aim might be to isolate only certain organs to express human genetic material, the whole chimera will in fact comprise the genetic material of both humans and pigs. It is not a pig with a human pancreas inserted into it – it is a human-animal chimera, whose pancreas resembles a human’s, and whose other organs are a blend of pig and human. This could affect the chimera’s brain. Pablo Ross, the lead researcher in the pig experiment, is quoted by the BBC as saying: ‘We think there is very low potential for a human brain to grow.’ Even if in this particular case he is correct, given that some of this kind of research is indeed focused on neurons, it is possible that some future chimeras will develop human or human-like brains.
Where the genetic material of humans and animals are mixed, this might result in characteristics that we usually think of as having moral relevance. ‘Moral status’ is the standing or position of a being within a hierarchical framework of moral obligations. The moral status of a chimera entails relevant obligations to treat it in certain ways while it is alive, in virtue of its nature, and has implications for whether it is wrong to kill it. How should we respond to chimeras when we are uncertain of their moral status? At present, chimeras created in laboratories are destroyed as embryos. But in order to harvest organs, full gestation would be needed....
